Some TalkTalk subscribers are being given the opportunity to receive a free speed test worth £50.
According to the broadband provider, around 16 million new gadgets connected to the internet on Christmas Day, putting networks under greater strain.
TalkTalk web traffic trebled last Christmas compared to the previous year, and the firm is expecting a further 25 per cent uplift on December 25th 2011.
"Three-quarters of us will call friends and families this Christmas, while around 60 per cent will check their emails and email loved ones on the day," said Tristia Clarke, Commercial Director at the firm.
"Almost 40 per cent of people say that modern technology has brought their extended families closer together."
And a third feel that even if they are not with their friends and family this Christmas, they still feel a part of the festivities due to Facebook and Skype, Ms Clarke said.
She claimed that with more people going online at Christmas, it is "even more important than ever" that everyone enjoys a great internet experience over the holiday.
This is why the provider has decided to offer a free TalkTalk speed test and optimisation visit to certain customers - enabling them to optimise their internet experience.
A number of different factors can affect the broadband speeds received by customers, such as the distance they are from the local telephone exchange and the type of router they use.
But line quality also makes a difference to download speeds - and this is where the engineers may be able to help.
Ms Clarke explained that the firm's Bright Spark engineers have visited over 1,000 homes so far and helped them get an average speed increase of around 4Mb.
"To find out if you qualify just use the TalkTalk Speed Checker and also get some simple tips on how to improve your in-home set up yourself," Ms Clarke stated.
